Seen through old sash windows, a crinkle of brickwork
and ripple of wrought iron remind me that glass is liquid:
cool and viscous, it creeps earthwards through the centuries.
This thought occurred to me when looking out at the buildings in the picture. Then, of course, I felt obliged to go and research whether glass really is liquid or whether that’s just an old wives’ tale. The idea is discussed at some length and technicality in this paper.
I think the conclusion is that, although glass can be considered a super-cooled liquid, the variations in thickness of old glass are nothing to do with the pull of gravity. Still, I was trying to write poetry not science, so I’m leaving it as it is and will blame any inaccuracy on my fallible narrator.
*oops: I really did spell it that way and publish it without checking. I’ll blame the fallible writer for that; and the fact that it’d be distorsión in Spanish.
